Hi Vinod,

This patch series adds support for the Direct Memory Access Controller
variant in the Renesas R-Car V3U (R8A779A0) SoC, to both DT bindings and
driver.

Changes compared to v1:
- Add Reviewed-by,
- Put the full loop control of for_each_rcar_dmac_chan() on a single
line, to improve readability,
- Use two separate named regions instead of array,
- Drop rcar_dmac_of_data.chan_reg_block, check for
!rcar_dmac_of_data.chan_offset_base instead,
- Precalculate chan_base in rcar_dmac_probe().

This has been tested on the Renesas Falcon board, using external SPI
loopback (spi-loopback-test) on MSIOF1 and MSIOF2.

Thanks!
